What’s So Smart About It?

The self healing grid

Normal Configuration


A Fault Occurs


Flow of Fault Current Triggers

Faulted Circuit Indicators (FCIs)


Substation circuit breaker

trips a first time


Substation circuit breaker recloses….


…and trips again (lockout)


FLISR identifies faulted section by

comparing FCIs


FLISR opens switches to isolate

the faulted feeder section


FLISR Triggers Upstream Restoration


Downstream restoration of blinking section

Compare load with available capacity


Downstream restoration of blinking section

Compare load with available capacity

Pre-fault load

= 1 MW

Available Capacity =

2 MW


Capability exists, so…

Available Capacity =

2 MW

Pre-fault load

= 1 MW


FLISR closes switch to restore service

Via alternate supply line


Now FLISR checks for capacity to

Transfer last downstream section

Available Capacity = 1.5

MW

Pre-fault load

= 2 MW


In this case capacity does not exist so

downstream section is not restored

Pre-fault load

= 2 MW


MW


Options for the red substation….

Pre-fault load

= 2 MW


MW


These actions free enough capacity to

pick up last remaining section


Only one problem….


So, how has this changed?

• Introduction to Field Force

Visualization supplemental

project

• Data visualization in a

broader sense

• Data and visualization as a

commodity


Goals of the FFDV Supplemental Project

• Identify gaps in standards

• Demonstrate the use of low

cost platforms

• Demonstrate the use of low

cost communication media

• Prove value of in field

integration

• Prove value for large scale

outages

• Identify multiplatform issues.


Field Force Data Visualization

An integrated field force data

visualization and integration

tool for managing work and

maintaining any asset in the field.

Leveraging CIM, Augmented Reality and Context

Aware GIS


Definition – Common Information Model (CIM)

• In our context, it is a

semantic model of the

electric utility industry that

may be leveraged to create

standard messaging

between back office

systems --- or in our case,

tablet or other hardware in

the field.


Definitions – Augmented Reality

• Augmented reality (AR) is a

live, direct or indirect, view of

a physical, real-world

environment whose

elements are augmented by

computer-generated sensory

input such as sound, video,

graphics or GPS data.

• Not to be confused with

virtual reality – which

replaces a real world with a

simulated one.

Definition – Context Aware GIS

• Using the dynamic context of

mobile device users, caused

by the mobility and constant

change in the environment,

to deliver information.

• Aware of the spatial

environment surrounding the

user.

• Aware of the role (limiting

access) of the user.


From “Dumb” to “Smart”


Traditional Point-to-Point Integration

Characteristics

• Complex environment

• High integration costs

• High maintenance costs

• Message tracking – non-

existent

• Guaranteed delivery –

non-existent

• Frequent “broken”

interfaces.

There is no “leverage” of the information being exchanged


“Smart” Integration

Characteristics

• Enterprise semantic model

• Enterprise service bus

– Little or no custom code

– Lower integration cost

– Lower maintenance

costs

– Message tracking

– Guaranteed delivery

– Reliable.

Messages are agnostic of their origins


Example: Typical Elements of a Work Request

• Work ID

• Location

• A bill of materials (BOM)

• An estimated time of

completion is calculated and

a start or completion time is

calculated.

• Crew type (based on skill

sets or roles)

• Detailed work tasks.


So, how does this all work?



The Issue:

• Access to real-time data in the field has not progressed

• Getting data to the field is too expensive

• Getting the data from the field is too cumbersome

• The applications don’t interop

• Data is not accurate

The Impact:

• Work is not efficient

• Decisions in the field suffer.

• Potentially dangerous situation.

Multiple applications in the field isn’t a great leap forward



EPRI Solution:

• Build on a light weight, inexpensive platform.

• Leverage augmented reality capabilities.

• Messaging using CIM to multiple systems.

• Two way communications to back office systems.

Value:

• Lower cost of field force automation.

• Puts accurate data where it needs to be.

• Correct inaccurate GIS data.

• Spurs CIM development.

Benefits

• Inexpensive to deploy

• Inexpensive to maintain

• Applications

– Asset maintenance manuals

– Damage assessment

– Asset information access

– Switching communications

– Work-order information flow

– Real-time system status

validation

Field Work Becomes Easier and More Efficient


Example: Damage Assessment


Implications for Large Scale Outages

• Use “foreign” tablets in the

damaged service territory

• Provide tablets to

contractors

• Instantly recognize the

symbology of the host utility

• Share information as

necessary.

With technology and standards that apply across the

industry, you can:

Implications


Commoditization

• Commoditization occurs when consumers

can buy the same product or service from

different small or large businesses.

• Price is the only distinguishing factor in

commoditized products, because there is

no significant difference in quality or in

how consumers use these products.

• Companies usually cannot raise prices

because consumers can shop at

competitors offering the same or similar

products at lower prices.

• This process is enabled by standards or

de facto standards.

Electrical Metering, 9th Edition

Examples of Benefits of Commoditization

• C12.10 standard

– Mass production of meters

– Residential electrical meter ~ $20

• C12.18/C12.19 Optical port

• TX/RX Protocols

− Interoperable hardware: probes, hand held readers, etc.


Typical Distribution Control Center a

Few Years Ago

• Distribution System was operated

manually with wall- mounted

switching diagrams

• Mostly paper driven processes


Current Trend in Control Center

Design

• Increasing emphasis on “outside the fence” visualization

• Large mapboards disappearing from distribution control centers

• Use of stackable monitors for operator workstations – allows view of specific “area of responsibility”


What if we were to bring the same technology

inside the operations center?

• Geo-schematic view

• Geographic view

• Crew locations

• Fault locations

• Create a works order

• Assign to a crew

Advantage: Display technology independent of back end systems


Conclusions

• The combination of mobile technologies, standards

development and communications enables new ways to

access and view data.

• Integration – the ability to use data from multiple systems –

is available not only in the back office but in the field.

• Standardizing the symbology and visualization technology

has far reaching implications for mutual aid/large event

management.

• The same technologies – touch screens, standard symbols,

standard messages, etc. – can be leveraged inside the

operations center with likely gains in efficiency and quality

decisions.
